This is the question I am stuck on - A. Create a CollegeCourse class. The class contains fields for the course ID (for example, CIS 210), credit hours (for example, 3), and a letter grade (for example, A). Include get and set methods for each field. Create a Student class containing an ID number and an array of five CollegeCourse objects. Create a get and set method for the Student ID number. Also create a get method that returns one of the Student’s CollegeCourses; the method takes an integer argument and returns the CollegeCourse in that position (0 through 4). Next, create a set method that sets the value of one of the Student’s CollegeCourse objects; the method takes two arguments—a CollegeCourse and an integer representing the CollegeCourse’s position (0 through 4). B. Write an application that prompts a professor to enter grades for five different courses each for 10 students. Prompt the professor to enter data for one student at a time, including student ID and course data for five courses. Use prompts containing the number of the student whose data is being entered and the course number—for example, Enter ID for student #1, and Enter course ID #5. Verify that the professor enters only A, B, C, D, or F for the grade value for each course. After all the data has been entered, display all the information in order by student then course as shown: Student #1 ID #101 CS1 1 -- credits. Grade is A CS2 2 -- credits. Grade is B CS3 3 -- credits. Grade is C CS4 4 -- credits. Grade is D CS5 5 -- credits. Grade is F This is the code I have so far, I am not sure if I have it all correct though, especially under the Student class I feel I am missing some stuff - public class CollegeCourse { private String courseID; private int credits; private char grade; public String getID() { //write code here return courseID; } public int getCredits() { //write code here return credits; } public char getGrade() { //write code here return grade; } public void setID(String idNum) { //write code here courseID = idNum; } public void setCredits(int cr) { //write code here credits = cr; } public void setGrade(char gr) { //write code here grade = gr; } } ---------------------------------------------------------- import java.util.*; public class InputGrades { public static void main(String[] args) { // Write code here } } ---------------------------------------------------------- public class Student { private int stuID; private CollegeCourse[] course = new CollegeCourse[5]; public int getID() { //write code here return stuID; } public CollegeCourse getCourse(int x) { //write code here if(x >= 0 && x <= 4) return courses[x]; else return null; } public void setID(int idNum) { //write code here stuID = idNum; } public void setCourse(CollegeCourse c, int x) { //write code here if(x >= 0 && x <= 4) c [x] = c; } }

Question

This is the question I am stuck on -

A. Create a CollegeCourse class. The class contains fields for the course ID (for example, CIS 210), credit hours (for example, 3), and a letter grade (for example, A). Include get and set methods for each field. Create a Student class containing an ID number and an array of five CollegeCourse objects.

Create a get and set method for the Student ID number. Also create a get method that returns one of the Student’s CollegeCourses; the method takes an integer argument and returns the CollegeCourse in that position (0 through 4). Next, create a set method that sets the value of one of the Student’s CollegeCourse objects; the method takes two arguments—a CollegeCourse and an integer representing the CollegeCourse’s position (0 through 4).

B. Write an application that prompts a professor to enter grades for five different courses each for 10 students. Prompt the professor to enter data for one student at a time, including student ID and course data for five courses. Use prompts containing the number of the student whose data is being entered and the course number—for example, Enter ID for student #1, and Enter course ID #5. Verify that the professor enters only A, B, C, D, or F for the grade value for each course. After all the data has been entered, display all the information in order by student then course as shown:

Student #1 ID #101 CS1 1 -- credits. Grade is A CS2 2 -- credits. Grade is B CS3 3 -- credits. Grade is C CS4 4 -- credits. Grade is D CS5 5 -- credits. Grade is F

This is the code I have so far, I am not sure if I have it all correct though, especially under the Student class I feel I am missing some stuff -

public class CollegeCourse {

private String courseID;

private int credits;

private char grade;

public String getID() {

//write code here

return courseID;

}

public int getCredits() {

//write code here

return credits;

}

public char getGrade() {

//write code here

return grade;

}

public void setID(String idNum) {

//write code here

courseID = idNum;

}

public void setCredits(int cr) {

//write code here

credits = cr;

}

public void setGrade(char gr) {

//write code here

grade = gr;

}

----------------------------------------------------------

import java.util.*;

public class InputGrades {

public static void main(String[] args) {

// Write code here

}

----------------------------------------------------------

public class Student {

private int stuID;

private CollegeCourse[] course = new CollegeCourse[5];

public int getID() {

//write code here

return stuID;

}

public CollegeCourse getCourse(int x) {

//write code here

if(x >= 0 && x <= 4)

return courses[x];

else

return null;

}

public void setID(int idNum) {

//write code here

stuID = idNum;

}

public void setCourse(CollegeCourse c, int x) {

//write code here

if(x >= 0 && x <= 4)

c [x] = c;

}
